. and Envelop, of Which the following is a speciiication.

This invention appertains to the class of articles of stationerycomprising in a single structure means `for receiving a communicationand means for closing and sealing the letter-sheet upon which themessage or mattei' has been inscribed.

The chief object of the invention is economy of material, cheapness ofmanufacture, and the avoidance of annoyance and inconvenience in the useof thearticle both when writing a letter' and when folding and sealingthe same.

The invention consists, essentially, of a letter-sheet provided at itsupper end with a gummed sealing-flap located at a point between theedges of the'sheet and a sealing-tab at one of the vertical edgesadjacent to the line of transverse folding, so as to secure the sheetwhen folded at the end opposite to the end closed by the sealing-ap.

The invention will be more particularly set forth hereinafter anddefined in the appended claim and is illustrated in the drawings heretoattached, in Which- Figure 1 is a view of the letter-sheet as seen fromthe rear side after 'being folded and sealed. Fig. 2 is a detail viewshowing the letter-sheet folded or doubled upon itself. Fig. 3 is adetail view of the letter-sheet spread out, the dotted lines indicatingthe folds.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The letter-sheet is indicated at 1 and is provided at its upper end Witha sealing-flap 2 and at one edge with a sealing-tab 3, both the liiapand tab being gummed for securance of A Serial No. 170.986. (No model.)

the sheet when folded in the accustomed Way. The dotted lines indicatethe several folds. The letter-sheet after being written upon is foldedupon itself along the transverse line a c, thence upon the verticallines b b and c c,

so as to present the form about as shown in Fig.. 1. The closing flap' 2is arranged between the lines t and c c, and the sealingtab 3 is locatedadjacent to and at one side of the transverse line c a. When theletter-sheet is folded,'the sealing-flap 2 is at one end and folds overthe several parts and closes the same and is gummed to the back of thepackage and to each of the side portions. The sealing-tab 3 is arrangedso as to occupy a position at the outer lower corner of one sideportionv and is adapted to overlap and be gummed to the opposite sideportion, thereby ysecuring the folded side portions at the end vor toone side of the center thereof or whether the sealing-tab is arrangedabove or below the line a, a or at the right-hand or at the left-handedge of the sheet, as the ultimate results are substantially the same.
